Dilip age was three times as old as his son
D = 3S
two years hence, twice his age will be equal to five times that of his son.
2(D + 2) = 5(S + 2)
Replace D on left hand side with 3S
2(3S + 2) = 5(S + 2)
6S + 4 = 5S + 10
6S - 5S = 10 - 4
S = 6.
Dilip is aged 20 years old
Son is 8 years old
Hope this helps.
